Dialog Semiconductor identified a new business opportunity using a breakthrough technology for touch screen devices. The global markets for such interactive devices are enormous in areas such as All-in-One PCs, Tablets, monitors, TVs etc.
Dialog were working in partnership with the technology company FlatFrog Laboratories AB who had developed the underlying optical touch technology and required the design of a new ASIC in order to fully commercialise the technology for mass product roll out.
Dialog asked Argon Design to co-manage development of the ASIC as well as providing the bulk effort for the technical and development work. The ASIC had to be designed from scratch to engineering samples in 6 months!
In partnership with Dialog's engineering team, the pertinent steps in achieving the challenge were as follows:-
Despite minor issues and delays, the chip taped out 5 ½ months after project start!
Following fabrication, an initial batch of 2500 samples was received from the Foundry for validation and qualification (see diagram below).
The "Bring Up" platform was designed to re-use much of the simulation "Verification Framework". This approach meant a proven set of tests and familiar environment was being used and allowed rapid bring-up of the first devices.
The "Bring Up" platform was used for design verification, validation, qualification and was used to test in total more than 3000 devices for prototype production - see one of our engineers in action in the diagram below.
The first version of the chip was fully functional.
(Dialog DA8901 Multi-Touch IC developed in partnership with Argon Design Ltd)
The customer was able to integrate the new ASIC into their technology and showed a working touch screen 8 days after receiving tested samples.
Development Kits (see diagram below) were created and packaged professionally for the Dialog and FlatFrog's engineering teams to perform further product testing and qualification.
